Back labor?

Hayley • 25, mommy to Milo 👦🏻💙 and Ollie 👶🏼💗

I need back labor stories. I’m 39+4 and I’m having excruciating lower back pain, I’m in tears because of it and while my pregnancy has been far from comfortable, I’ve never been in tears over back pain. I’m at Walmart, I have to do some shopping and plan on picking up a heat pack to see if that helps, but Tylenol isn’t cutting it.
